Precision test charts for more accurate results

In general, the image quality of scanners and cameras is tested using charts that are a degree better than the expected test result of the device under test.

The TE240, which measures the dynamic range according to ISO 21550, is available as a transparent and reflective chart. In reflection, the achievable contrast is limited to about 2.4 densities. In transmission, the user can select between 4.0 and 6.0 densities. The IT8 color target (TE258) is the standard target for color profiling, and we provide it in a reflective and a transmissive version with a broad color gamut.

The TE250 (transparent test chart) is used for visual resolution measurement for scanners, according to ISO 16067, and is done traditionally with the slanted edge target QA-62 (reflective)
